With all but 1 other fan base, I would just assume that anyone that posts that level of stupidity is 14 years old or less and I would just move on.
With the cult and the DFBIA, the culture creates diagnosable, they-should-put-them-in-the-DSM-VI conditions. Literally anyone, given enough time in those cultures, could post stuff like that as an adult; we've seen it so many times.
There are probably other fan-bases that diseased; having lived in Tallahassee I can think of one off-hand. But those two are the ones that we are regularly subjected to that produce that level of... hmm, what to call it... it's not "thought"... ... I'll go with "commentary". Only the cult and the dfbia give us that level of commentary. You can't use the word "thought" when talking about them, unless you're using it to say you can't use it.
